You are right, the reason why some newbies believe that Bitcoin will drop below $30k is because someone that introduced them into Bitcoin investment gave them that impression and mindset however as a newbie you need to do some research about Bitcoin yourself, you need to know the history of Bitcoin investment and how's is going.
Of course when you’re new to something you will only have the knowledge your mentor teaches you even if there are right or wrong you only have knowledge of what is be taught to you. Newbies are not to rely only what they are taught you should have the ability to carry out personal research on your own to widen your knowledge just as it is in school. Bitcoin is different from other cryptocurrencies and and even though we will experience a dip in price no one is quite sure how deep it will fall but I don’t think we might see $30k price. When you are a long time investor you don’t have to worry about the price dips at all all you should be focused on is accumulating more and more bitcoin. This should be the mindset of every newbie.
As a newbie into Bitcoin investment it is important you know that waiting for a dip to happen before you can start accumulating is a waste of time, talk more of waiting for it to drop below $30k, if you want to start Bitcoin investment you don't have to wait for a dip, you can use the DCA strategy by accumulating weekly or monthly using your Discretionary income.
Waiting for the perfect market dip can be a futile strategy. What if it doesn't happen as anticipated, or not in time? Instead of delaying, consider investing smaller amounts regularly using the Dollar-Cost Averaging (DCA) strategy. This approach makes investing more accessible, especially for newbies. When the dip does occur, you can take advantage of it, but don't let waiting hold you back from investing altogether.
